Title: Method for reducing over-range image artifact in tamographic imaging
Inventor: JIYAN SHII
IPC: G06T5/20
Filed: 1992-11-25
Abstract: PURPOSE: To reduce image artifact, by estimating an alternate value to an over-range part discriminated by a threshold detector, and combining it with the data of an in-range part. CONSTITUTION: An over-range part 21' is coped with an X-ray crossing to only an edge of an imaging object 12 and an edge of a bow-shaped filter 32. A raw projection 36 is compared with the ADC maximum value 39 by the threshold operation, and an over-range mask 40 is generated. On the other hand, the raw projection data 36 is multiplied by an inverse function representing the supplement, to obtain a density profile 44 by determining the negative number of the logarithm. A boxcar nucleus 75 and a trapezoidal signal 88 generated from a superpose integrator from the over-range mask 40, have a half of the additional slope S necessary for correcting the data of a clipped channel 46, on the basis of slope 58 discriminated by the calculation of slope 72. The trapezoidal signal is clipped, and a slice image is formed by multiplying a produced correction mask 78 by the density profile 44.  An image reconfigurating unit 68 is suitably used for all the pipeline processings.

Title: System for generating servo pattern for magnetic head positioning
Inventor: OI FUKASHI
IPC: G11B5/596
Filed: 1987-12-14
Abstract: PURPOSE:To attain head positioning with highly precision by providing silent parts between four kinds of adjacent bursts in prescribed lengths when a two- phase servo pattern is generated. CONSTITUTION:At the time of positioning a servo head 1, the servo head 1 reads four kinds of bursts consisting of a positive A phase AP, a positive B phase BP, a negative A phase BP and a negative B phase BP as servo signals. The read servo signals are added to a full wave rectification circuit 13, are full wave-rectified, and are fetched as an A position signal 15 and a B position signal 16 through integrating circuits 14 and 14'. Since the non-recording parts in the prescribed lengths are provided between four kinds bursts at that time, components due to the adjacent burst are prevented from mixing into a rectification output even if there is the circuit delay of gate delay and clock delay at the time of full wave rectification, and therefore the occurrence of errors can be prevented. Thus, highly precise positioning is attained.

Title: Color cathode-ray tube
Inventor: CHIHARA KAZUHIRO
IPC: H04N9/29
Filed: 1987-12-11
Abstract: PURPOSE:To prevent a drop in color purity due to an external stray magnetic field by providing an external magnetic shield with a diagonal side extension part nearing and covering the diagonal part of a vacuum enclosure. CONSTITUTION:The diagonal part of an external magnetic shield 7 is provided with a diagonal side extension part 7c for connecting a long-side extension part 7a to a short side extension part 7b along the diagonal part of a panel part. And this diagonal side extension part 7c is provided with a notch 7d for passing a fitting member. When a magnetic field is applied in four orthogonal directions, the diagonal side extension part 7c of the external magnetic shield 7 becomes a passage for a line of magnetic force, because of the position thereof near the diagonal part of a color cathode-ray tube. And a magnetic flux flows toward the long side extension part 7a. Also, the notch 7d for passing the fitting member is formed at the diagonal side extension part 7c and, therefore, a leak magnetic flux is generated at the notch 7d. As the extension part 7c is so shaped as to be appropriate for a magnetic field passage, however, the aforesaid leak magnetic flux can be made extremely small, compared with a leak magnetic flux at the diagonal part of the external magnetic shield 7.

Accordingly, the quantity of penetration at the thin plate 2 side increases and a nugget 5 is formed spreading over both thick plate 1 and thin plate 2. By this method, the occurrence of lack of fusion is reduced and the welding cost is reduced as the inexpensive electrodes are used.

IPC: H01L21/205
Filed: 1994-12-20
Abstract: PURPOSE: To obtain a sufficient crystal growth rate and the high utilization efficiency of a raw material by simultaneously introducing a raw material substance consisting of an organometallic compound containing a group III element and a compound containing a nitrogen element and active hydrogen atoms to a substrate surface section in a reaction vessel. CONSTITUTION: When a nitride semiconductor crystal is grown by using an organometallic compound comprising a group III element, a reaction vessel 13 is supplied with the organometallic compound without previously decomposing the organometallic compound. Nitrogen and hydrogen are decomposed by plasma, and supplied as active nitrogen atoms and active hydrogen atoms. Active atoms formed in plasma are carried by a gas flow, and a section near the surface of a substrate 14 is fed with active atoms.  Accordingly, since the decomposition rate of the organometallic compound, in which active hydrogen atoms are concerned, is increased remarkably, the organometallic compound is decomposed sufficiently for a slight time when the organometallic compound exists on the surface of a nitride semiconductor, thus remarkably accelerating the growth rate of the nitride semiconductor crystal, then improving the utilization efficiency of a raw material substance.
